Precision Fuel & Hydration
Precision Fuel & Hydration is a British sports nutrition brand founded by sports scientist Andy Blow — a former Brownlee Brothers nutritionist and Ironman athlete — around a concept that was revolutionary when he proposed it: that different athletes lose dramatically different amounts of sodium in sweat, and that a one-size-fits-all electrolyte product cannot optimise hydration for everyone.

What Is Precision Fuel & Hydration? PH 500 is their entry electrolyte product — 500mg of sodium per serving for athletes with average sodium losses. PH 1000 is their high-sodium product — 1,000mg of sodium per serving for heavy sweaters or athletes competing in hot conditions. PH 1500 is their extreme formula. All products are available as sachets, multi-serve pouches, or pre-mixed drinks. Precision Fuel & Hydration also produce carbohydrate products — Carb 90 sachets and Pre-Load hydration — forming a complete fuelling and hydration system. Why Choose Precision Fuel & Hydration?
